Landscape edging system having block attachment member

ABSTRACT

A landscape edging system and corresponding components and methods are disclosed. The system comprises an edging member having a top rail and a barrier extending downwardly therefrom, and corresponding interconnecting or adjoining blocks, each block having at least one block attachment member disposed on the bottom surface thereof for receiving top rail therewithin. The blocks, in combination with the edging member, may be employed to separate adjoining lawn, garden, walkway, driveway or other areas from one another. The present invention permits the effects of undesired displacement forces acting on the blocks, such as frost heave, to be reduced or minimized.

FIELD OF THE INVENTION

The present invention relates to landscape edging systems, methods andcomponents, and to paving block edging systems, methods and componentsfor forming borders or walkways between adjoining garden, landscape,driveway, walkway, patio or sidewalk areas.

BACKGROUND OF THE INVENTION

Gardeners, landscapers and homeowners frequently use border or edgingmaterial such as fences, logs, railroad ties, bricks, concrete blocksand the like to provide a decorative edge for a landscape or garden.Such border or edging material is also frequently employed to physicallyseparate landscape, garden and other areas from one another.

Plastic landscape edging is now commonly used to divide and separatedifferent landscape areas to preclude material in one area from spillingover into an adjacent area, and to prevent grass, flowers or the likecontained in one area from growing in an adjoining area. For example,plastic edging is typically used to divide grass landscape areas fromadjoining garden areas, and helps prevent grass from taking root inadjoining garden areas. Plastic edging also helps prevent garden beddingmaterial from spilling onto the adjoining landscape area. The mostprevalent materials used to fabricate landscape edging today are inert,synthetic flexible plastics such as polyethylene and ethylene vinylacetate.

In the past, landscape edging has been formed from lengths of wood,corrugated metal strips, plastic, cement blocks and poured concrete.Wood is subject to rot and insect attack and decays over time. Woodlandscape timbers must therefore be replaced rather frequently.Ungalvanized metal bands oxidize and rust, and tend to become bent andmisshapen over time. Even galvanized to metal bands eventually corrodeonce the protective zinc coating has been oxidized. Concrete blocks areinflexible, difficult to install and generally heavy. Poured concrete isexpensive, difficult or impossible to modify once poured and set, anddifficult and time-consuming to install.

Plastic landscape edging, on the other hand, is inexpensive, readilymanufactured, flexible and has a long service life. As a result of thedisadvantages inhering in wood, metal and concrete landscaping materialsand the unique advantages of plastic, plastic landscape edging hasbecome the landscape edging material of choice of many consumers.

While landscape edging formed from inert synthetic plastic has manyadvantages such as being flexible and resisting deterioration well,problems nevertheless occur in their use. Conventional landscape edgingusually consists of a longitudinally extending strip of material havinga lower edge that is inserted into the ground to a predetermined depthand an upper edge or rail that generally projects above the ground. Theedging is typically installed by digging a narrow trench, inserting thelower edge to a predetermined depth, refilling the trench and compactingthe earth around the edging. Such installation normally maintains theedging in its intended position for a period of time.

As time progresses, however, the environment and other factors activelywork against the edging remaining in its original position. The edgingmay be walked on, bumped, kicked, shoved aside or otherwise engaged insuch a manner that it is displaced in respect of its original position.Landscape mowers or tractors may repeatedly drive over the edging anddisplace or damage the edging.

The winter effects of frost heave, or the freezing and thawing action ofthe earth surrounding the edging, are often more severe than theforegoing effects in respect of edging displacement or damage. Theground retains moisture in the fall that freezes with droppingtemperatures. Water is one of the few materials having a coefficient ofvolume expansion that increases as temperature decreases, and the groundaccordingly expands with frozen moisture in the winter. This has theeffect of compressing and heaving the landscape edging, and as a resultthe edging breaks or is laterally or vertically displaced. When springarrives in colder climates, plastic landscape edging is often found tohave buckled upwards and protruded from the ground during the winter inresponse to frost heave, especially where adjacent strips of edging areconnected to one another. As temperatures rise in spring, the moisturebeneath the ground surface melts, again changing the volume of thesubsurface ground adjoining the edging. As the seasons alternate, thelandscape edging is repeatedly exposed to a variety of forces arisingfrom changing soil volumes that, over the long term, cause the edging tobecome dislodged or damaged.

Landscape edging systems, components and methods are well known in theart, some examples of which may be found in the issued U.S. Patentslisted in Table 1 below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As used in the specification and claims hereof, the following terms havethe particular meanings and definitions set forth below.

The terms “block” “landscape block,” “landscape edging block” and“paving block” mean a block suitable for use in at least one oflandscaping, walkway or driveway applications.

The term “conventional landscape edging barrier” means a landscapeedging barrier formed of plastic, such as those disclosed in U.S. Pat.Nos. 3,378,949 to Dorris; 3,387,786 to Rynberk; 3,484,989 to Lazinsky;3,485,449 to Wilson; 3,788,001 to Balfanz, Jr.; 4,281,473 to Emalfarb etal.; 4,644,685 to Tisbo et al.; 4,761,923 to Reum et al.; 4,761,923 toReum et al.; 4,809,459 to Brylla et al.; 4,858,379 to West; 4,969,289 toTrifiletti; 5,067,273 to Richwine; 5,121,569 to Thomas; 5,201,154 toThomas; 5,438,804 to Reum et al.; 5,501,036 to Torp, Jr. et al.;5,519,970 to Reum et al. and 5,535,545 to Matz.

The terms “lawn edging member,” “landscape edging barrier,” “landscapeedging member,” “strip barrier” and “edging barrier” are substantiallysynonymous, and mean an edging member formed of metal, plastic or othersuitable material that is configured for use in at least one oflandscape, walkway or driveway applications.

FIGS. 1(a) through 1(c) show one embodiment of landscape edging system 5of the present invention. Landscape edging member 10 is preferablyelongated, and has top rail 14 for separating adjacent lawn, garden,walkway or patio areas. Top rail 14 has edging barrier 20 extendingdownwardly therefrom for placement in ground 400. At least a portion oftop rail 14 is affixed to or forms part of upper portion 24 of edgingbarrier 20 such that top rail 14 protrudes or extends above groundsurface 404 when at least lower portion 28 of edging barrier 20 ispositioned beneath ground surface 404 in ground 400. The ends oflandscape edging member 10 are preferably configured for connection toadjoining similar members 10 by any of several well known means, such asby connecting member 16 shown in FIG. 2(b), to thereby form asubstantially continuous downwardly extending barrier 20 and top rail14.

Any of a variety of known landscape edging members find application incertain embodiments of the present invention. For example, landscape orlawn edging members of the types disclosed in U.S. Pat. Nos. 3,378,949to Dorris; 3,387,786 to Rynberk; 3,484,989 to Lazinsky; 3,485,449 toWilson; 3,788,001 to Balfanz, Jr.; 4,281,473 to Emalfarb et al.;4,644,685 to Tisbo et al.; 4,761,923 to Reum et al.; 4,761,923 to Reumet al.; 4,809,459 to Brylla et al.; 4,858,379 to West; 4,969,289 toTrifiletti; 5,067,273 to Richwine; 5,121,569 to Thomas; 5,201,154 toThomas; 5,438,804 to Reum et al.; 5,501,036 to Torp, Jr. et al.;5,519,970 to Reum et al. and 5,535,545 to Matz find particularefficacious and advantageous application in certain preferredembodiments of the present invention.

Landscape edging member 10 is most preferably formed of a plastic suchas polyethylene or ethylene vinyl acetate. Other elastomeric, polymericor synthetic materials are also suitable for forming landscape edgingmember 10. Landscape edging member 10 is most preferably formed byextruding and molding a synthetic material that is resilient, flexible,inert, UV resistant and further capable of withstanding wide variationsin ambient temperature and humidity.

One significant drawback to most plastics finding application inlandscape edging member 10 of the present invention is the relativelyrapid breakdown of such plastics, and resulting deleterious effects,caused by exposure to ultra-violet (or UV) radiation. It is an advantageof the present invention that landscape edging member 10 is protected orshielded by block 60 from UV radiation by block 60. As a result,landscape edging member 10 of the present invention, when formed ofplastic, does not break down or degrade as quickly in use in comparisonto landscape edging members of the prior art that relativelycontinuously exposed to harmful UV radiation.

FIGS. 1(a) through 1(c) further show landscape edging block 60 havingbottom surface 64, opposing ends 68 and 72, and imaginary longitudinalaxis 76 extending between the opposing ends 68 and 72. Bottom surface 64has substantially longitudinally disposed recess 80 formed therein.Recess 80 is configured to receive at least a portion of top rail 14therein, and extends over at least a portion of bottom surface 64. Twoopposing ends 68 and 72 of block 60 are configured to engage, abut, orinterconnect with the corresponding opposing ends of other adjoininglandscape edging blocks 60 attached to the top rail by their respectiverecesses. Recess 80 is configured to receive at least a portion of topedge 14 therein, and extends over at least a portion of bottom surface64. Most preferably, top rail 14 and recess 80 form complementaryshapes, and are configured to prevent or impede block 60 from beingremoved from top rail 14 when an upward or lateral force is exerted uponblock 60 and top rail 14 is disposed in recess 80.

As shown in FIG. 1(c), at least a portion of edging barrier 20 extendsdownwardly from the bottom surface of each block 60 into ground 400 whenrecesses 80 corresponding to each block 60 receive their correspondingat least portions of top rail 14 therein. Bottom surfaces 64 of theplurality of engaging, abutting or interconnected landscape blocks 60may be disposed along or beneath ground surfaces 404. The embodiment ofthe present invention shown in FIG. 1(c), and other embodiments similarto it, lend themselves particularly well to installation applicationswhere blocks 60 are retrofitted on existing, installed landscape edgingbarriers having conventional circular cross-section top rails 14. Suchretrofitting avoids the requirement for removal of existing landscapeedging members 10 and re-installation of new, differently configuredlandscape edging members 10.

FIGS. 2(a) through 2(u) show perspective views of selected lawn edgingmembers 10 of the present invention. Top rails 14 of the presentinvention having various structural configurations are also illustratedin FIGS. 2(a) through 2(u). FIGS. 3(a) through 3(t) show cross-sectionalviews of selected lawn edging members 10 and blocks 60 of the presentinvention; top rails 14 of the present invention having variouscross-sectional configurations are illustrated therein, along withcorresponding blocks 60 having recesses 80 formed to receive top rails14 therein.

It will now become apparent to those skilled in the art that a virtuallyunlimited range of suitable cross-sectional shapes exists for top rail14 and corresponding recess 80 of block 60 of the present invention. Forexample, top rail 14 may be T-shaped, round, elliptical, triangular,square, rectangular or nearly any other suitable shape in cross-section.Recess 80 is most preferably formed to receive top rail 14 engagingly,snugly or tightly therein, and thus preferably assumes a shapecomplementary to that of top rail 14.

Lower portion 28 and central portion 30 of landscape edging member aremost preferably shaped or configured to include means for anchoringlandscape edging member 10 in ground 400. For example, lower portion 28may include an anchor member having a triangular cross-section, whereinthe apex of the triangle points downwardly as in U.S. Pat. Nos.5,438,804 and 5,519,970 to Reum et al. See also, for example, FIGS.2(a), 2(b), 2(e), 2(f), 2(h), 3(d) and 3(g) herein. In other embodimentsof the present invention, however, and as shown in FIGS. 3(u) through3(oo), recess 80 need not conform to the shape of at least the bottomportion of top rail 14. Instead, recess 80 may be configured to receivetop rail loosely therein.

Central portion 30 and lower portion 28 may also have a plurality ofhollow, molded projections extending from one or both faces, where theinterior of each projection is open on the opposite face correspondingto the portion, and the portion forms a concave soil socket or nestingregion that becomes filled with soil when landscape edging member 10 isinstalled in ground 400. See, for example, U.S. Pat. Nos. 5,201,154 toThomas and 4,761,923 to Reum et al and FIGS. 2(c), 2(d), 2(f), 2(k),2(l), 2(m), 3(c), 3(e), 3(f), 3(h), 3(i), 3(j), 3(k), 3(l), 3(p), 3(q)and 3(r) hereof.

Alternatively, central portion 30 or lower portion 28 may include amedial or longitudinal downwardly or upwardly pointing rib or end hookas in U.S. Pat. No. 5,410,458 to Bell. Blades, flanges, ears or securinglips of the types disclosed in U.S. Pat. Nos. 5,501,036 to Torp, Jr. etal., 3,788,001 to Balfanz, Jr., 4,644,685 to Tisbo and 4,281 to Emalfarbet al. may extend outwardly and upwardly or outwardly and downwardlyfrom central portion 30 or lower portion 28 to form a means foranchoring landscape edging member 10 in ground 400. See, for example,FIGS. 2(e), 2(g), 2(j), 2(n), 2(o), 2(p), 2(t), 2(u), 3(a), 3(b), 3(o),3(s) and 3(t) hereof.

Metal or plastic stakes may be driven at an oblique angle throughbarrier 20 after landscape edging member 10 has been installed in ground400 to better secure landscape edging member 10 in the ground. See, forexample, FIG. 2(s) herein.

Landscape edging member 10 is most preferably sufficiently flexible andstructurally configured to permit ready packaging in coiled fashion.See, for example, U.S. Pat. Nos. 5,519,970 to Reum et al., where lawn orlandscape edging members are disclosed that lend themselves particularlywell to being packaged in coiled fashion. See also FIG. 2(l) herein.

Landscape edging member 10 may also form a strip of the type disclosedin U.S. Pat. No. 5,456,045 to Bradley et al., where top edge or rail 14is configured for withstanding hammering, the bottom edge of lowerportion 28 is configured for penetration in ground 400, and edgingmember 10 has ends constructed for interlocking with adjacent strips ormembers.

FIGS. 4(a) through 4(b) show a variant of landscape edging system 5 ofthe present invention, where adapter clip 32 is disposed between innersidewalls 82 of recess 80 and the outer surface of top rail 14. Adapterclip 32 has arms 35 and 37 that expand apart to accept top rail 14therebetween when adapter 32 is pushed downwardly onto top rail 14. Arms35 and 37 also preferably engage inner sidewalls 82 of recess 80 whenblock 60 is disposed atop clip 32 and top rail 14. Adapter clip 32 ispreferably configured to permit block 60 having recess 80 of width 84 tosuitably interconnect with and engage top rail 14, regardless (withinreasonable bounds) of width 36 of top rail 14. Thus, adapter clip 32permits block 60 to be fitted onto the top rail of any of a number ofvarious different commercially available brands of lawn edging, many ofwhich share no common top rail width 36. It will become apparent tothose of ordinary skill in the art that adapter clip 32 may be formed inmany configurations other than C-shapes.

FIGS. 4(c) through 4(f) show steps for installing system 5 of FIGS. 4(a)and 4(b) in ground 400, where block 60 and adapter clip 32 are installedon existing landscape edging member 10. FIGS. 4(g) through 4(l) show avariant of the embodiment of the invention illustrated in FIGS. 4(a)through 4(f) where recess 80 is configured to permit compensation forvertical height shifts or changes in ground surface 404 to occur betweenor along blocks 60.

FIGS. 4(j) and 4(k) show another variant of landscape edging system 5 ofthe present invention, where clip-on adapter 33 is interposed betweenblock 60 and rail 14. Clip 32 is preferably formed as a portion of clip33, and snaps onto top rail 14. Block 60 may merely sit on adapter 33.Alternatively, and more preferably, recess 80 of block 60 mayfrictionally engage and receive adapter 33 therewithin. Siderails 27 and29 receive and may frictionally engage the side portions of block 60.

FIGS. 5(a) and 5(b) show another embodiment of the landscape edgingsystem of the present invention, where block 60 has a plurality ofvertically-aligned recesses 80(a), 80 (b) and 80(c) formed therein.Those recesses permit bottom surface 64 of block 60 to conform snuglywith the laterally changing elevations of ground surface 404 in respectof top rail 14. Recesses 80(a) through 80(c) also permit bottom surface64of block 60 to conform well with ground surface 404 despite variationsin the depth to which downwardly extending barrier 20 is buried inground 400.

In the embodiment of the landscape edging system of the presentinvention shown in FIGS. 5(a) and 5(b), top rail 14 is received withinthe highest recess top rail 14 can reach and engage. FIG. 5(a) shows anexploded perspective view of landscape edging system 5. FIG. 5(b) showsa cross-sectional view of landscape edging system 5 installed in ground400, where top rail 14 engages recess 80(b). As shown in FIGS. 5(a) and5(b), which of recesses 80(a), 80(b) or 80(c) top rail 14 mostpreferably fits within and engages depends upon the distance between toprail 14 and ground surfaces 404. In FIG. 5(a), top rail 14 barelyprotrudes above ground surface 404 and therefore most preferably engagesrecess 80(a). In FIG. 5(b), top rail 14 protrudes a large distance aboveground surface 404 and therefore most preferably engages recess 80(c).

Is FIGS. 6(a) and 6(b) show yet another embodiment of the presentinvention. Landscape edging 10 has a longitudinally disposed rib or toprail 14 that is adapted to engage one of recesses 80(a), 80(b), 80(c) or80(d), depending on the relative distance between top rail 14 and groundsurfaces 404. In FIG. 6(a), rail 14 engages and fits most preferably inrecess 80(a) owing to the large distance between top rail 14 and groundsurfaces 404. In FIG. 6(b), rail 14 engages and fits most preferably inrecess 80(c) owing to the small distance between top rail 14 and groundsurfaces 404.

It will now become apparent to those of skill in the art from theforegoing teachings set forth herein that a virtually unlimited numberof recesses 80 having different configurations, orientations, shapes andnumbers, and various combinations thereof, may be disposed in block 60and fall within the scope of the present invention.

FIGS. 7(a) and 7(b) show another variant of the present invention, wherelandscape edging member 10 has a plurality of top rails 14 disposedthereon for engaging or fitting within one or more recesses 80 in block60. In FIGS. 7(a) and 7(b), top rails 14(a), 14(b) and 14(c) mostpreferably form flexible or malleable ribs that are longitudinallydisposed along upper portion 24 of barrier 20. Top rails 14(a), 14(b)and 14(c) are configured to fit within at least one of recesses 80(a),80(b) and 80(c) according to the distance between top rail 14(a) andground surfaces 404.

In FIG. 7(a), rail 14(a) most preferably engages and fits in recess80(a) owing to the small distance between top rail 14(a) and groundsurface 404; rails 14(b) and 14(c) fit within no recesses owing to thesmall distance. In FIG. 7(b), rail 14(a) engages and fits mostpreferably in recess 80(c) owing to the large distance between top rail14(a) and ground surface 404; top rails 14(b) and 14(c) most preferablyfit within and engage recesses 80(b) and 80(a), respectively. Rails14(a) through 14(c) also preferably bias or grip block 60 downwardly orin proximity to ground surface 404 through the combined action of thedownwardly angled ribs of top rails 14(a), 14(b) and 14(c) andcorresponding recesses 80(a), 80(b) and 80(c).

FIGS. 7(c) and 7(d) show yet another variant of the invention of FIGS.7(a) and 7(b), where landscape edging member 10 has a plurality of toprails 14 disposed thereon for engaging or fitting within one or morerecesses 80 in block 60. In FIGS. 7(c) and 7(d), the plurality of toprails 14 most preferably form flexible or malleable ribs that arelongitudinally disposed along upper portion 24 of barrier 20. Theplurality of top rails 14 are configured to fit within at least one ofthe plurality of recesses 80 according to the distance between top rails14 and ground surfaces 404. Optional collapsible cores 87 permit toprail 14 to more snugly engage recess 80 through a frictional fittherewithin.

Another embodiment of the present invention includes that shown in FIG.8, where recesses 80(a) and 80(b) in block 60 are oriented substantiallyperpendicular to imaginary axis 76 and receive therein corresponding toprails 14(a) and 14(b), also oriented substantially perpendicular toimaginary axis 76. Thus, recesses 80(a) and 80(b) and corresponding toprails 14(a) and 14(b) of the present invention may be oriented along anyazimuth or direction, and are not limited to embodiments where recesses80 and top rails 14 are disposed longitudinally or substantiallyparallel to imaginary axis 76.

FIGS. 9(a) through 9(l) show several additional embodiments of block 60of the present invention, where blocks 60 have at least one additionalrecess 81 disposed therein, or an enlarged recess 80 disposed therein,for lightening and reducing the amount of material required to formblocks 60, for permitting landscape edging member 10 to bend morereadily when imaginary axes 76 of blocks 60 are rotated respecting oneanother, or for accepting sprinkler fittings, sprinklers, plumbingmeans, electrical power cords or light emitting means therein.

Blocks 60 shown in FIGS. 9(a) through 9(c) need not form a flat,substantially smooth surface for engaging ground surfaces 404. Instead,the various bottom surfaces 64 shown in FIGS. 9(a) through 9(c) providevertical support for blocks 60 on ground surface 404 using legs 65 and66, while recesses 80 extend downwardly from bodies 61 of blocks 60 forsuitable engagement with top rails 14. The blocks shown in FIGS. 9(a)through 9(l) may provide landscape blocks of lighter weight.Additionally, those blocks generally require less material for theirmanufacture than do the blocks of FIGS. 1 through 8. Other methods andconfigurations for coring out block 60 to reduce weight and the amountof material required for its formation will now become apparent to thoseof skill in the art, such as those where bottom surface 65 is flat orsubstantially flat, but block 60 is nevertheless cored.

As shown in FIGS. 9(d) through 9(j), blocks 60 may be formed accordingto a number of alternative configurations or shapes to provide enlargedor specially shaped recesses 80 that permit edging member 10 to bendmore readily when imaginary axes 76 of adjoining blocks 60 rotaterespecting one another.

As shown in FIGS. 9(k) and 9(l), blocks 60 may be formed according to anumber of alternative configurations or shapes to provide recesses 80for accepting sprinkler fittings or sprinklers 105, plumbing means 103,electrical power cords 101 or light emitting means 173.

Blocks 60 of the present invention may be formed of any of a number ofmaterials, including, but not limited to, ceramic, fired clay, glass,recycled glass, glass, stone, rock, cement, concrete, mortar, varioussuitable conglomerate materials, untreated wood, treated wood(includingso-called brown and green treated wood), virgin plastic, recycledplastic, polyurethane, polyethylene, TREX® (a composite material sold byMobil Corporations® for use in decking boards and the like), fiberglass,various composite or artificial materials such as low-to-medium densitypolyethylene combined with sawdust or the like, or fiberglass combinedwith sawdust or the like. Those of ordinary skill in the art will nowappreciate that other materials than recited specifically herein findapplication in, and fall within the scope of, the present invention.

Interlocking or adjoining blocks of the type that may be adapted rathereasily for particularly efficacious application in the present inventioninclude, but are not limited to, those disclosed in U.S. Pat. Nos.3,762,113 to O'Mullan et al.; 4,695,502 to Rush; 5,078,940 to Sayles;5,080,523 to Steiner; 5,117,583 to Reum; 5,119,587 to Waltz; 5,133,163to Christensen et al.; 5,217,630 to Sayles; 5,233,806 to Hightower etal.; 5,375,369 to VerHoeve; 5,414,956 to Kheradpir; 5,535,568 to Quinn;5,564,240 to Dean, Jr. and Des. 335,429 to Scott, Jr. et al. Adjoiningblocks 60 may interconnect by having adjoining surfaces that: (a)overlappingly engage one another; (b) laterally or horizontally engageone another; (c) both laterally and overlappingly engage one another;(d) vertically engage one another only, and do not overlap eitheroverlappingly or laterally, and (e) otherwise engage, abut or restpropinquant to one another.

For example, as shown in FIG. 10(a), each block 60 may have relativelyshort length 77, correspondingly shaped vertical surfaces 68(a) and68(b) and correspondingly shaped horizontal surfaces 72(a) and 72(b) formatingly or overlappingly engaging adjoining blocks 60. Short length 77permits joints between adjoining blocks 60 to be less obvious than theywould otherwise appear in the presence of rapid or large changes in theslope of ground 404.

FIG. 10(b) shows compound lap joints in blocks 60 of the presentinvention, where adjoining vertical surfaces 68(a) and 68(b) are convexand concave, respectively, and horizontal surfaces 72(a) and 72(b)overlap one another. Like blocks 60 in FIG. 10(a), relatively largevariations in elevation in ground surface 404 do not cause large orunsightly joints or cracks to appear between adjoining blocks 60 in FIG.10(b). FIG. 10(c) shows a cross-sectional view of block 60 of FIG.10(b). FIGS. 10(d), 10(e), 10(f) through 10(k), 10(r) through 10(v) and10(x) show further embodiments of block 60 of the present invention,where adjoining blocks 60 overlap or otherwise engage one another.

Alternatively, adjoining blocks 60 may have not only complementaryshapes for engaging one another, but other structural features forpositively securing one block to the next. For example, blocks 60 mayhave corresponding holes 77 and vertically-oriented pins 78 havingoptional tips 79 for engaging one another as shown in FIGS. 10(l)through 10(q) and 10(w). Blocks 60 may have horizontally-oriented pins78, as shown in FIG. 10(x). In other embodiments of the presentinvention, blocks 60 interconnect by bolt and nut means or by screwmeans.

Another means of interconnecting blocks 60 of the present invention isby corresponding slot and tab means. In preferred embodiments of thepresent invention, adjoining or interconnecting blocks 60 may rotate atleast slightly in respect of one another, thereby permitting blocks 60to form a curved or winding border or barrier.

As shown in FIGS. 10(z) and 10(jj), some embodiments of block 60 of thepresent invention may have formed on one or both lateral or top surfacesthereof a lip or surface for receiving lawn mower wheels thereon. Such aconstruction permits lawn grass to be cut by a mower only, without anysubsequent need to trim grass adjoining blocks 60 after mowing, or to becut more easily by a power or hand lawn trimmer after mowing. Block 60of the present invention may be configured to have mowing lips orsurfaces of the types disclosed in U.S. Pat. Nos. 3,777,421 to Bomba etal., 5,517,867 to Fritch, 5,377,447 to Fritch, 5,544,445 to Mantilla.

FIGS. 10(z) through 10(cc) show adjoining blocks 60 being configuredsuch that overlapping portions conceal or sit atop preferably at leastpartially planar top surfaces 75 of anchoring stakes 76 positioned inrecesses 180(a), after installation has been completed. FIG. 10(ee)shows a variant of the present invention, where anchoring stake 76 issubstantially U-shaped. Pointed ends 76(a) and 76(b) are inserted intosoil 400 after recess 80 of block 60 has engaged top rail 14. Block 60may be configured to receive more than one such U-shaped anchoring stakein sleeve 190.

FIGS. 10(ff) and 10(gg) show another embodiment of the presentinvention, where blocks 60(a), 60(b) and 60(c) form herb or flowerblocks interposed between blocks 60. FIG. 10(ff) shows blocks 60, 60(a),60(b) and 60(c) in an exploded perspective view. FIG. 10(gg) showsblocks 60, 60(a), 60(b) and 60(c) in an assembled or connectedperspective view. Herb or flower blocks 60(a), 60(b) and 60(c) eithersingly or collectively form central recess 71 for receiving soil ormulch and accompanying flowers, herbs, small shrubs or small bushestherein. Central recess 71 most preferably has drain holes 72 formed onthe bottom surface thereof.

As shown in FIGS. 10(ff) and 10(gg), blocks 60, 60(a), 60(b) and 60(c)most preferably have interlocking or overlapping joints at the abuttingor adjoining ends thereof. In the embodiment of the present inventionshown in FIGS. 10(ff) and 10(gg), edging member 10 may be terminated ateither side of herb or flower blocks 60(a), 60(b) or 60(c).Alternatively, edging member 10 may extend through recesses 80 disposedin the bottom central portions of herb or flower blocks 60(a), 60(b) or60(c). In the embodiment of the present invention shown in FIGS. 10(ff)and 10(gg), lawn edging member 10 preferably includes top rail 14, andneed not include edging barrier 20.

Upon reading the specification of the present invention as disclosedherein, it will now be seen by those of skill in the art that many othervariations and embodiments of blocks 60, 60(a), 60(b) or 60(c) arepossible, and that those variations or embodiments likewise fall withinthe scope of the present invention.

FIGS. 10(hh) through 10(kk) show clips 32 disposed generally on bottomsurfaces 64 of blocks 60 in recesses 80. Clips 32 have arms 35 and 37that expand apart to accept top rail 14 therebetween when adapter 32 ispushed downwardly onto top rail 14. Arms 35 and 37 may or may not engageinner sidewalls 82 of recesses 80 when blocks 60 are disposed atop toprail 14. Clips 32 are preferably configured to permit block 60s havingrecesses 80 of various widths to suitably interconnect with and engagetop rails 14, regardless (within reasonable bounds) of the width of toprail 14. Thus, clips 32 permit blocks 60 to be fitted onto the top railsof any of a number of various different commercially available brands oflawn edging, many of which share no common top rail width.

Tabs or projections 91 may be formed along the outer surfaces of clips32 for securing blocks 60 to clips 32. As shown in FIGS. 10(hh) and10(ii), clips 32 may have only one projection or tab 91 formed therein.Alternatively, and as shown in FIGS. 10(jj) and 10(kk), more than onetab or projection 91 may be formed in clips 32 of the present invention.Tabs or projections 91 may be inserted into corresponding recessesformed in undersides 64 of blocks 60 for frictional engagementtherewith, or may be formed into block 60 at the time block 60 is formedfrom cement, plastic, mortar or the like. Alternatively, tabs orprojections 91 may be glued or otherwise secured to blocks 60.

FIG. 10(kk) shows how clips 32 may be formed to provide not only meansfor securing blocks 60 to top rails 14, but also to provide means forhousing electrical cable 101 or water hose 102. Electrical cable 101 maybe routed through blocks 60 to illumination blocks (not shown) forproviding light at dusk or nighttime to adjoining walkway or gardenareas. Water hose 102 may be routed through blocks 60 to sprinklerfixtures (not shown) for providing water to adjoining garden or lawnareas.

FIGS. 10(ll) through 10(oo) illustrate embodiments of the presentinvention particularly well adapted to curved or winding installations.Front and rear surfaces 68 and 72 of blocks 60 are curved to permitready installation of adjoining blocks 60 along winding or curved toprail 14, where downwardly extending barrier 20 may or may not dependtherefrom. Optional sprinkler head 105 may be fitted in block 60, as mayoptional electric power cord 101 and water hose or plumbing means 103.

FIGS. 10(ll), 10(pp) through 10(aaa), and 10(ccc) show embodiments oflandscape edging system 5 of the present invention where edging members10 have no or substantially no barrier member 20 extending downwardlytherefrom. Instead, top rails 14 fit within recesses 80 of blocks 60 orare secured thereto by clips 32. Stakes 76 are optional, but preferablysecure landscape edging member 10 and top rail 14 to ground surfaces404. When stakes 76 are employed in conjunction with landscape edgingmember 10, it is preferred that member 10 be secured first to groundsurface 404 by stakes 76, followed by blocks 60 and clips 32 beingpushed downwardly onto top rail 14 for attachment thereto. Additionally,trenches 195 may be formed to receive bottom surfaces 64 of blocks 60therein, or no such trenches may be formed such that system 5 is“trenchless.”

FIG. 10(bbb) shows another embodiment of landscape edging system 5 ofthe present invention, where edging member 10 has horizontally-orientedribs 11 disposed on edging barrier 20. Ribs 11 help edging member 10remain secured in ground 400.

FIGS. 10(eee) through 10(nnn) show various embodiments of the presentinvention particularly well suited for erosion control or soilcontainment, and corresponding methods of installing same. FIGS. 10(eee)through 10(kkk) illustrate one method of the present invention whereblock 60 is installed on sloping ground surface 404 atop top rail 14having no or substantially no downwardly extending barrier 20 dependingtherefrom. Block 60 is configured to retain garden soil 405 therein orprevent the downslope erosion thereof.

FIGS. 10(lll) through 10(nnn) illustrate another method of the presentinvention where block 60 is installed on sloping ground surface 404using stake 76. Block 60 is configured to retain garden soil 405 thereinor prevent the downslope erosion thereof. Stake 76 is received in a holedisposed through block 60 which permits stake 76 to be installed over awide range of angles respecting the vertical.

FIGS. 10(ooo) through 10(rrr) show various alternative embodiments ofblocks 60 having at least one attachment member 32 secured to the bottomsurface 64 thereof. Each block 60 has bottom surface 64, two opposingends 68 and 72, and imaginary longitudinal axis 76 extending between thetwo opposing ends. Bottom surface 64 has at least one attachment member32 secured thereto and extending over at least a portion of bottomsurface 64. At least one attachment member 32 receives at least aportion of top rail 14 therein. Two opposing ends 68 and 72 of eachblock 60 are configured to engage, abut, or interconnect with thecorresponding opposing ends of other adjoining landscape edging blocks60.

FIGS. 10(ooo) through 10(rrr) show that top rail 14 and at least oneattachment member 32 are most preferably configured to prevent or impedeblock 60 from being removed from top rail 14 when an upward or lateralforce is exerted upon block 60 and top rail 14 is disposed withinattachment member 32. Such forces may be imparted by frost heave, lawnmower wheels, automobile wheels, children and the like. It is preferredthat at least a portion of edging barrier 20 extend downwardly intoground 400 from bottom surface 64 of each block 60 when at least oneattachment member 32 corresponding to each block 60 receives itscorresponding at least portion of top rail 14 therein and bottomsurfaces 64 of a plurality of engaging, abutting or interconnectedlandscape blocks 60 are disposed along or beneath ground surfaces 404.

Attachment member 32 may assume any of a number of different structuralconfigurations, some of which are illustrated in FIGS. 10(ooo) through10(rrr). FIG. 10(ooo) shows attachment member 32 forming a C-shaped tubeconnected to bottom surface 64 of block 60. FIG. 10(ppp) showsattachment member 32 forming a rail for receiving corresponding top rail14 having a circular cross-section. FIG. 10(qqq) shows attachment member32 being formed from one or a plurality of individual attachmentcomponents 32(a), 32(b) or 32(c) for engaging, gripping or otherwisesecuring top rail 14. FIG. 10(rrr) shows attachment member 32 forming arail having a T-shaped recess disposed therein for receiving top rail 14having a corresponding T-shaped cross-section. Many other similarconfigurations for attachment member 32 and top rail 14 will now be seenby those of skill in the art to be possible, and to likewise fall withinthe scope of the present invention.

In another embodiment of the landscape edging system of the presentinvention, and as shown in FIG. 10(sss), elongated landscape edgingmember 10 comprises top rail 14, top surface 15, bottom portion 28 andtwo opposing substantially vertically-oriented surfaces definingstrip-shaped barrier member 20. Barrier member 20 extends downwardlyfrom top rail 14 for placement in ground 400.

FIG. 10(ttt) shows a cross-sectional view of edging member 10 of FIG.10(sss). In FIG. 10(ttt), recess 80 in block 60 receives at least aportion of top rail 14 therein. Recess 80 extends over at least aportion of bottom surface 64. Top rail 14 and recess 80 are mostpreferably(but not necessarily) configured to prevent or impede block 60from being removed from top rail 14 when an upward or lateral force isexerted upon block 60 and top rail 14 is disposed in recess 80.

In the embodiment of the landscape edging system of the presentinvention shown in FIGS. 10(sss) and 10(ttt), landscape edging member 10may be formed of corrugated metal or plastic strips having, for example,a T-shaped top rail 14. While edging members having such configurationsare not at present manufactured in great volumes and therefore are notreadily available to consumers at the present time, they nonethelesslend themselves particularly well to new installation applications whereblocks 60 are not retrofitted on existing, installed landscape edgingbarriers having conventional circular cross-section top rails 14.

Top surface 15 of top rail 14 may also be configured and formed of amaterial suitable for receiving hammer blows thereon to easeinstallation of edging member 10 in ground 400. For example, T-shapedtop rail 14 illustrated in FIGS. 10(sss) and 10(ttt) may be configuredfor receiving hammer blows on top surface 15, thereby easing theinstallation process in respect of conventional landscape edgingbarriers because no trench or only a shallow trench need be excavatedfor receiving landscape edging member 10.

FIG. 10(uu) shows another embodiment of the present invention, wherelandscape edging member 10 is formed of metal or plastic. In thisembodiment of the present invention, edging member 10 is most preferablyformed from a corrugated galvanized metal strip that is resistant tocorrosion and that lends itself to easy packaging.

FIG. 10(vvv) shows an embodiment of landscape edging system 5 of thepresent invention where edging member 10 has cut-out portions 17 formedalong the top edge thereof. Cut-out portions 17 are formed mostpreferably by cutting or perforating strip 10 using a stamping die orthe like. Cut-outs 17 are preferably configured to fold downwardly whena sideways or downward force F is applied thereto as shown in FIG.10(vvv). As shown in FIG. 10(www), cut-out portions 17 form wings ortabs when after having been folded downwardly and outwardly. Wings ortabs 17 engage or fit within recess 80 of block 60. Cut-out portions 17and top surface 16 most preferably form surfaces for receiving hammerblows thereon to ease installation. In accordance with other embodimentsof the present invention disclosed herein, edging member 10 may includesoil anchoring means such as pockets, concave dimples or harpoon-likebottom edge portion, or function in cooperation with anchoring stakes orother like devices.

FIG. 10(xxx) shows an embodiment of landscape edging system 5 of thepresent invention where top surface 15 of barrier member 10 has aplurality of pins or members 19 that extend upwardly therefrom. Upwardlyextending members or pins 19 engage corresponding holes, recesses orslots 80 in block 60 that are appropriately configured for receivingpins or members 19. It will now become apparent to those skilled in theart that many possible structural configurations exist for upwardlyextending member 19. Slots or recesses 80 are disposed along bottomsurface 64 of block 60, and are configured lo receive members 19. Asshown in FIG. 10(xxx), upwardly extending members 19 most preferablyhave edges or ribs that grip or fit within corresponding edges or ribsdisposed within recesses or slots 80 of block 60. Such ribs or edgesdownwardly bias block 60 against top surface 15 and ground surface 404once block 60 has been positioned over members 19 and pressed downwardlythereupon.

Another embodiment of landscape edging system 5 of the present inventionis illustrated in FIG. 11, where landscape edging block anchoring member12 is employed to secure landscape edging block 60 to ground surfaces404. Anchoring member 12 most preferably comprises upper portion 7 andlower portion 9 connected by central body portion 6. Upper portion 7 isconfigured to protrude or extend above ground surface 404 when lowerportion 9 is positioned beneath ground surface 404 in ground 400. Upperportion 7 defines a predetermined shape in cross-section and mostpreferably an at least partially planar top surface 3 suitable forreceiving blows from a hammer thereon. Lower portion 9 is mostpreferably pointed and shaped for insertion into the ground as blowsfrom a hammer are received on the at least partially planar top surface3 or as anchoring member 12 is otherwise pushed or forced into ground400.

Anchoring member 12 is most preferably configured to prevent or impedeblock 60 from being removed from upper portion 7 of anchoring member 12when an upward or lateral force is exerted upon block 60 and top portion7 is disposed in recess 80. Anchoring member 12 is also most preferablyformed of a material such as wood, plastic or metal that is sufficientlymechanically robust to withstand the forces ordinarily or typicallyassociated with pushing, forcing or hammering anchoring member 12 intoground 400.

Anchoring member 12 may be disposed in recess 80 of block 60, where themajor axis of recess 80 is aligned substantially parallel to imaginarylongitudinal axis 76. Alternatively, anchoring member 12 may be disposedin a recess having a major axis that extends substantially perpendicular(or in any other direction) in respect of imaginary longitudinal axis76. For example, a recess having a cross-sectional shape correspondingto the cross-sectional shape of anchoring member 12 and for receivingsame therein may extend through block 60 at substantially right anglesto imaginary longitudinal axis 76; at least partially planar top surface3 of anchoring member 12 would then most preferably be co-planar withtop surface 65 of block 60 upon being inserted in the recess.

In another embodiment of the present invention, anchoring member 12 isconfigured for use with at least one attachment member 32. Block 60 hasbottom surface 64, two opposing ends 68 and 72, and imaginarylongitudinal axis 76 extending between the two opposing ends. Bottomsurface 64 has at least one attachment member 32 secured thereto andextending over at least a portion thereof. At least one attachmentmember 32 has recess 80 formed therein. The cross-sectional shape ofrecess 80 corresponds to at least a portion of the predeterminedcross-sectional shape of upper portion 7 of anchoring member 12.Attachment member 32 is configured to receive at least a portion ofupper portion 7 therein to permit anchoring member 12 to be secured toblock 60.

Two opposing ends 68 and 72 of block 60 are configured to engage, abut,or interconnect with the corresponding opposing ends of other adjoininglandscape edging blocks 60. Each block 60 is secured to ground surface404 by its corresponding anchoring member 12 that extends downwardlytherefrom into ground 400 from bottom surface 64 or attachment member 32of each block 60. Bottom surfaces 64 of the plurality of engaging,abutting or interconnected landscape blocks are disposed along orbeneath ground surface 404.

Anchoring member 12 may be formed of a substantially rigid material suchas metal or any of a number of suitable metal alloys, or of a somewhatpliable material such as SANTOPRENE®, neoprene, or any of a number ofsuitable plastics, synthetic rubbers, plastics, polyethylene,polyurethane, neoprene, ethylene vinyl acetate, elastomeric material,polymeric material, metal, metal alloy, galvanized steel, untreatedwood, treated wood, and the like. If a somewhat pliable material isemployed to form anchoring member 12, a trowel or other suitable toolmay be used to excavate a hole in soil 400 for receiving anchoringmember 12 therein, thereby obviating the need to pound anchoring member12 into soil 400 by striking at least partially planar top surface 3.

As shown partially in FIG. 11, anchoring member 12 may have at least oneor a plurality of barbed members, harpoon-like members 14, soil pockets,ribs, ridges, concave dimples, nesting regions, blades, flanges, ear,securing lips, or end hooks disposed thereon for securing anchoringmember 12 in ground 400. More preferably yet, lower or central portions9 or 6 may include soil pockets, ribs or ridges for securing anchoringmember 12 in ground 400.

FIGS. 12(a) and 12(b) show an embodiment of the present inventionparticularly well adapted for paving block walkway or drivewayapplications. FIG. 12(a) shows an exploded perspective view of pavingblock system 130. FIG. 12(b) shows a perspective view of assembledsystem 130. Blocks 60 are disposed atop bottom barriers 140 and adjacentone another to form a driveway or walkway whose edges are defined byoptional side barriers 135. Top rails 14 of bottom barriers 140 engageand are received within corresponding recesses 80 of blocks 60 tothereby secure blocks 60 to bottom barriers 140. Adjoining side andbottom barriers 135 and 140 interconnect with one another. Paving blocksystem 130 need not include optional side barriers 135.

In a preferred embodiment of the present invention. bottom barriers 140are configured for horizontal placement on excavated ground surface404(b). Side barriers 135 are most preferably configured to extendupwardly and vertically such that its uppermost surface is flush orprotrudes a slight distance above ground surface 404(a). Bottom barriers140 may also be placed on a ground surface that is not excavated; sidebarrier 135 in such a case would extend upwardly from ground surfaces404.

Substantially vertically oriented side barriers 135 attach tosubstantially horizontally oriented bottom barrier by means ofinterconnecting tabs 151 and slots 152, where tabs 151 slide into andare biasingly engaged within correspondingly disposed slots 152 inbottom barriers 140 when tabs 151 are inserted substantially completelyinto slots 152. Adjoining substantially horizontally oriented bottombarriers 140 similarly attach to one another by means of interconnectingtabs 151 and slots 152. Adjoining substantially vertically oriented sidebarriers 135 likewise attach to one another by means of interconnectingtabs 151 and slots 152.

FIGS. 12(c) and 12(d) show another embodiment of the present inventionparticularly well adapted for paving block patio, walkway or drivewayapplications. FIG. 12(c) shows an exploded perspective view of anotherembodiment of the paving block system 130. FIG. 12(d) shows aperspective view of assembled system 130 of FIG. 12(c). Blocks 60 aredisposed atop bottom barriers 140 and adjacent one another to form apatio, walkway or driveway whose edges are defined by optional sidebarriers 135. Top rails 14(a) of bottom barriers 140 engage and arereceived within corresponding recesses 80(a) of blocks 60 to therebysecure blocks 60 to bottom barriers 140. Side rails 14(b) of blocks 60engage and are received within recesses 80(b) of adjoining blocks 60 orside barrier 135. Side barrier 135 shown in FIGS. 12(c) and 12(d) hasside rail 14(c) for engaging and being received within correspondingrecess 80(b) of block 60. Adjoining side and bottom barriers 135 and 140interconnect with one another. Paving block system 130 shown in FIGS.12(c) and 12(d) need not include optional side barriers 135.

The embodiment of the present invention shown in FIGS. 12(c) and 12(d)provides superior structural integrity to paving block system 130 owingto the manner in which most or all components of the system interlock orinterconnect to one another. Such a system provides superior resistanceover time to undesired displacement forces such as frost heave. It willnow become apparent to those skilled in the art that many variants ofthe respective geometries of the recess and corresponding rail systemillustrated are possible, and that such variants fall within the scopeof the present invention.

The present invention includes within its scope any of a wide variety ofdifferent means for interconnecting bottom and side barriers 140 and135, such as means for screwably, glueably, pinnably, tongue andgroovably interconnecting such barriers to one another. It will nowbecome apparent to those skilled in the art that many other means forinterconnecting side and bottom barriers 135 and 140 may be employed,and that such alternative means fall within the scope of the presentinvention.

Bottom and side barriers 140 and 135 may form one contiguous piece, ormay form separate pieces or components. Likewise, a plurality of bottombarriers 140 or side barriers 135 may be formed into a single contiguoussheet, or may form separate components as shown in FIGS. 12(a) and12(b). FIGS. 12(a) and 12(b) show left-hand substantially verticallyoriented side barriers 135, but do not show corresponding right-handsubstantially vertically oriented side barriers 135 for defining thewidth of paving system 130. We note that such right-hand substantiallyvertically oriented side barriers 135 should have slots 152 disposedtherein, as opposed to tabs 151 (as shown in FIG. 12(a)), for receivingtabs projecting horizontally from bottom barriers 140.

A user may select the number of bottom barriers 140 required to form apatio, walkway or driveway of a desired width. Likewise, a user mayselect the number of bottom barriers 140 and side barriers 135 requiredto form a patio, walkway or driveway of a desired length. In a preferredembodiment of the present invention, bottom barriers 140 and sidebarriers 135 have drainage holes formed through the surfaces thereof topermit rain water and the like to drain therethrough. In a mannersimilar to the structures shown in FIGS. 2(s), 10(z) through 10(ee),10(mm), 10(nn), and 11, anchoring stakes may be driven through bottombarriers 140, side barriers 135 or blocks 60 to secure those componentsto ground surface 404. It is also contemplated in the present inventionthat side and bottom barriers 135 and 140 have optional edging barriers20 (not shown in FIGS. 12(a) or 12(b)) depending downwardly therefromfor better securing system 130 to ground surfaces 404.

It is preferred that side and bottom barriers 135 and 140 be configuredand interconnect in such a way that the major axis azimuth ororientation 160 of a first width-wise course of bottom and side barriers140 and 135 may differ at least slightly from the major axis azimuth ororientation 160 of an adjacent second width-wise course of bottom andside barriers 140 and 135, thereby permitting system 130 to form awinding or curving walkway or driveway. End surfaces 68 and 72 of blocks60 may also be shaped or configured to permit changes in orientationfrom one width-wise course to the next by, for example, roundingsurfaces 68 and 72 as shown in FIGS. 10(b), 10(e), 10(f) through 10(w).Many other means of permitting such changes in orientation from onewidth-wise course of paving blocks to the next will now become apparentto those skilled in the art.

Bottom barriers 140 have may top rails 14 formed in the top surfacesthereof. If so, top rails 14 are disposed along azimuths or imaginaryaxes corresponding to the orientations of axes 76 of blocks 60 andrecesses 80. Azimuths and orientations of top rail 14 other than thoseshown in FIGS. 12(a) and 12(b) are contemplated in the presentinvention. For example, top rails 14 may be oriented perpendicular toaxes 76 in a manner similar to that shown in FIG. 8.

FIGS. 12(a) and 12(b) further show a plurality of paving blocks 60 insystem 130. Each block 60 has top surface 65, bottom surface 64, twoopposing end surfaces 68 and 72, and two opposing side surfaces 67 and69. Two opposing end surfaces 68 and 72 and bottom surface 64 mostpreferably have a longitudinally disposed recess 80 formed therein forreceiving at least a portion of top rail 14 therewithin to secure block60 to bottom barrier 140. Other azimuths or orientations of recess 80are contemplated in the present invention. Two opposing end surfaces 68and 72 of each block 60 are most preferably configured to engage, abut,or interconnect with corresponding opposing end surfaces of otheradjoining landscape edging blocks 60 attached to top rail 14 by theirrespective recesses 80.

Inside surface 136 of side barrier 135 is configured to receivethereagainst side surfaces 67 or 69 of blocks 60 aligned end to end,while bottom barrier 140 is configured to receive thereon bottomsurfaces 64 of blocks 60. At least a portion of bottom barrier 140 orside barrier 135 extends downwardly for placement in soil 400. Forwalkway and driveway applications, blocks 60 are most preferably formedof materials resistant to hot, dry, wet and cold climates and suitablefor paving applications such as fired clay, formed concrete and thelike.

It will now become apparent to those skilled in the art that pavingblock system 130 of the present invention may form a structurally robustpaving block underlayment and restraint system. Moreover, top rails 14and recesses 80 in blocks 60 of system 130 most preferably function toprevent or impede dislodgment of blocks 60. The various components ofsystem 130 most preferably interact and function together in such amanner to ameliorate the deleterious effects of frost heave bypreventing or impeding the movement of blocks 60.

Another method of the present invention is similar to theabove-described method but permits easier formation of a trench forreceiving edging barrier 20. More particularly, trench formation device190 and corresponding installation methods shown in FIGS. 14(a) through14(uu) may be employed by a user to aid in forming one or more trenches195 in ground 400.

In FIG. 14(a), cutting member 197 forms a portion of device 190, and isreceived by or attached to handle 198. As a user pushes device 190 alongsurface 404 using handle 198, cutting member 197 slices into ground 400and forms twin trenches 195. FIGS. 14(b) through 14(d) show various mansfor attaching handle 198 to cutting member 197.

FIGS. 14(e) through 14(h) show one method of forming twin trenches 195using tool 190, where tool 190 is guided along top rail 14 of existingedging member 10. As often occurs in conventional edging systems, thepoints at which adjoining strips of edging member interconnect are frostheaved to the surface as shown in FIG. 14(e). Connecting member 16 maybe employed to reconnect the adjoining strips of edging, as illustratedin FIG. 14(f).

FIGS. 14(m) through 14(q), 14(r) through 14(v), 14(w) through 14(aa),14(bb) through 14(ee) illustrate yet further methods and embodiments ofthe present invention. In FIGS. 14(m) through 14(q) and 14(r) through14(v) tool 190 is employed to form twin trenches 195 for receivingundersides 64 of blocks 60 therein, and edging member 10 has no orsubstantially no bottom barrier extending downwardly therefrom. In FIGS.14(w) through 14(aa), no tool 190 is employed to form trenches 195.Instead, stakes 76 are driven through top rail 14 having no orsubstantially no bottom barrier extending downwardly therefrom, notrench is dug or excavated, and blocks 60 are disposed atop top rail 14once stake 76 has been driven through the top surface of top rail 14. InFIGS. 14(bb) and 14(cc), and FIGS. 14(dd) and 14(ee), tool 190 may ormay not be employed to form twin trenches 195 for receiving undersides64 of block 60 therewithin.

In FIG. 14(ff), cutting member 197 is a disk, forms a portion of device190, is received by or attached to handle 198. As a user pushes device190 along surface 404 using handle 198, cutting member 197 slices intoground 400 and forms trench 195. Footrest 199 permits device 190 to bepushed along top rail with relative ease. FIG. 14(gg) shows across-sectional view of FIG. 14(ff). FIG. 14(hh) shows a variant of theinvention shown in FIGS. 14(ff) and 14(gg). As shown in FIG. 14(ii),disk or cutting member 197 may be stowed in a sideways storage positionagainst handle 198 when not in use. As shown in FIG. 14(hh), pin 194 maybe employed to interconnect disk 197, frame 193, and optional foot rest199.

Device 190 may, of course, be motorized simply enough be providing anappropriate internal combustion or electric motor and correspondingtransmission means for driving cutting member 197 or for pushing device190 forwardly. For example, known rotary tilling machines may bemodified in accordance with the teachings presented herein to replacetheir rotary tilling blades and means with a rotating trench formationblade 197 which cuts trench 195 in soil 400. Optionally, such amotorized device may be driven forwardly by motorized drive means astrench 195 is cut.

Disks having different diameters may be received by device 190 to permittrenches having different depths to be formed as shown in FIGS. 14(jj)through 14(mm). Trench formation device 190 may be configured toaccommodate different size disks or cutting members 197 as shown inFIGS. 14(ll) and 14(oo). FIGS. 14(nn) and 14(pp) show grooved roller 196which may be included in device 190. It is preferred that disk 197 havea V-shaped or wedge-shaped cross-section such that it forms a trenchhaving a top portion of greater width than the bottom portion.
